Abstract
The invention discloses low-cost and long-service-life lubricating oil, relating to the technical field of fine chemical engineering. The lubricating oil is prepared from the following raw materials in parts by weight: 70-90 parts of neutral base oil, 3-5 parts of dispersant, 3-7 parts of viscosity index improver, 5-8 parts of PKB900 type complex antioxidant, and 1-5 parts of KH570 silane coupling agent. The neutral base oil with higher viscosity index is taken as a main component, and the LHT7016 type viscosity index improver is added, thus obviously increasing the viscosity index of the lubricating oil; compatibility between an additive and the base oil of the lubricating oil is better, thus improving the stability of the lubricating oil; compared with existing lubricating oil, the lubricating oil is lower in production cost and longer in service life.
Description
Technical field
The present invention relates to technical field of fine, especially a kind of low-cost long-life lubricating oil.
Background technology
Lubricating oil to be used in automobile, mechanical means to reduce friction, protection machinery and the liquid of workpiece or semi-solid lubricants, mainly play lubrication, cooling, antirust, clean, seal and the effect such as buffering.Lubricating oil is made up of base oil and additive two portions, base oil is lubrication main body of oil, and decide the essential property of lubricating oil, additive then can make up and improve the deficiency of base oil aspect of performance, giving the performance that some is new, is the important component part of lubricating oil.Viscosity index refers to the temperature variant degree of oil viscosity, and viscosity index is higher, and represent that oil viscosity is less by the impact of temperature, its viscosity temperature characteristic is better, otherwise poorer; Viscosity index is the important indicator of lubricants performance, therefore, how to improve the focus that oil body index becomes current lubricating oil research field.
Summary of the invention
The object of this invention is to provide a kind of low-cost long-life lubricating oil, this lubricating oil can solve the low problem of existing lubricating oil viscosity index.In order to solve the problem, the technical solution used in the present invention is: this lubricating oil is prepared from by the raw material of following parts by weight: neutral base oil 70 parts ~ 90 parts, dispersion agent 3 parts ~ 5 parts, viscosity index improver 3 parts ~ 7 parts, PKB900 type composite antioxidant 5 parts ~ 8 parts, KH570 silane coupling agent 1 part ~ 5 parts.In technique scheme, technical scheme can also be more specifically: I, II, III class base oil of described neutral base oil to be viscosity index the be high viscosity index (HVI) of more than 90.
Further, described dispersion agent is glyceryl monostearate or Tristearoylglycerol.
Further, described viscosity index improver is LHT7016 type viscosity index improver.
Further, the parts by weight of described raw material are neutral base oil 90 parts, dispersion agent 3 parts, viscosity index improver 3 parts, PKB900 type composite antioxidant 3 parts, KH570 silane coupling agent 1 part.
Further, the parts by weight of described raw material are neutral base oil 80 parts, dispersion agent 5 parts, viscosity index improver 3 parts, PKB900 type composite antioxidant 3 parts, KH570 silane coupling agent 2 parts.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention is with the higher neutral base oil of viscosity index for main component, with the addition of LHT7016 type viscosity index improver, significantly improves oil body index.
2, lubricating oil additive of the present invention and base oil consistency better, improve the stability of lubricating oil.
3, the present invention is compared with existing lubricating oil, and its production cost is lower, Working Life of Lubricating Oil is longer.
